Hotbed glass locking mechanism

thingiverse

This is a new version of a mechanism to lock the glass plate on the hotbed when the glass is bigger than the hotbed itself. It is very simple and it is glued on the glass using 5minutes epoxy. There is a pattern on the bonding side to enhance the adhesion. In a previous model I glued it with silicone but with time it always failed so this time I used epoxy and it feels much better. The parts are printed, so they are not really suggested when using high hotbed temperatures, I never exceed 50 degrees as I print mostly PLA, but I think they should be ok with 70 or 80 degrees as they are on the outside and it doesn't get up to the same temperature as the area on the hotbed PCB. I filleted the screw holes of the PCB and used tapered screws. You can customize the size of the parts and the hotbed thickness to suit your needs.
